you can connect the hose from the water pump and hose that goes into intake manifold behind the alternator with a copper 1/2 inch or 5/8 90 degree fitting. maybe $2.00. and two 3/4 hose clamps. maybe another $2.00...

If it has ABS, you have to bleed them from the caliper upwards with a special unit that pressurizes the brake fluid in a bottle. Some also need a scan tool.

I am not sure if you are asking what these two fuses go to, or if you are trying to ask what amperage to install. I believe I'll need to know if you've looked on the inside of the access panel to see if there is a diagram for you. Sometimes there is a booklet in a pocket. But since your astro is 13 years old, it is probably missing. Please let me know what exactly your question is.

Have you checked your freon level? The compressor will not engauge when the R134 level is too low .More than likely you need to recharge the system after 14 yrs you may have a small seal leak. Try picking up a recharge kit with a gauge attachment. This has worked well for me on my 3 Astros I currently own. Othwise the fuse box is on the drivers side left of the steering column.

One line supplies vacuum from the intake manifold to the control panel. The other line runs back from the control panel to the heater water control valve, which is along the heater hose. The vacuum port on the valve is at the top of the cylindrical actuator.

What sensor ? VSS - vehicle speed sensor on the transmission ? Colud be the speedometer gauge is bad . Do you know how the insturment cluster get's that info. ? Your best bet , take it to a qualified repair shop . You have no idea how it works , don't have the diagnostic tool's to find the problem ,so do yourself a favor . The first step would be to hook up a factory or professional type scan tool to see if the VSS info is seen in the VCM ,then to see what the VCM is sending over the serial data network . Do you know what a serial data communication network is ? VCM is vehicle control module .
Speedometer and Odometer Circuit Description
An electronic speedometer is standard equipment on all models. Integrated circuits control the air core speedometer and the stepper motor odometer. Removable bulb and socket assemblies provide the lighting. The socket assembly inserts into the back of the instrument cluster.
The speedometer system consists of the following components:
• The instrument cluster
• The vehicle speed sensor (VSS) calibrator
• The VSS
• The related wiring
The VSS calibration is part of the VCM that changes the analog output from the VSS to a digital signal. The digital signal contains 4000 pulses per mile (PPM) for the instrument cluster. The VCM sends the signal to the speedometer through CKT 389. The VSS calibration matches to the final drive and the tire size of each vehicle. Reprogram the VCM with the proper VSS calibration if the final drive or tire size changes for any reason. The signal will not be accurate for the proper speedometer/odometer operation if the necessary change is not made. An incorrect VSS calibrator can also affect the following components:
• The antilock brakes
• The vehicle control module (VCM)
The cruise control systems
The VSS calibration is programmed into the VCM. Do not service the VSS calibrator separately.
The VSS is a permanent magnet signal generator that sends an analog signal proportional to the propeller shaft speed to the VCM. The VSS mounts to the transmission tailshaft extension housing on the two-wheel drive model. The VSS mounts to the transfer case output shaft housing on the all-wheel drive models.


Use a Scan Tool in order to read the vehicle control module (VCM) diagnostic trouble codes.
Are there any vehicle speed sensor related trouble codes?

You can try cleaning it, or just replace it.

If your looking to buy you can try amazon, ebay, or rock auto as well. Those are aftermarket vendors who are more than likely to have either Chilton or Haynes manuals. Other wise if you know a buddy at a shop or someone who has access to Michelle on demand or All Data, those will more than likely have what you need.
Hope this Helps.

There is no speedometer relay. The speedometer input is provided from the vehicle speed sensor that is located in the tailshaft portion of the transmission.
This input is also used by the power train control module (or PCM) and is used as an input for transmission shifting.

The answer is yes and no. If you are disconnecting the battery to check the alternator, that is not a recommended practice. To check your alternator all you have to do is check the voltage at the battery terminals with the vehicle completely off. You can use a cheap multimeter set to DC and a range of 15-20 volts. Record that value and then start the vehicle and check the voltage the same way. The voltage has to be at least 1-1.5 Volts higher than when the vehicle was off. if it's less, the battery is not getting charged.

Though this responce may be out of place n regards to an issue I had w/ my 97' astro van. It continued hearing a (rather annoying) clicking - ticking noise that would increase in speed (& just slightly louder) when I pressed on the accelerator, but when letting off, it would always slow back down to what it sounded like at idle speed. This went on for quite a long while, until I "shockingly" found that, in fact, that one of the wires (if I recall, it being the main coil wire) was arcing/sparking (clicking-ticking noise) on the transmission fill tube or dipstick tube. You could see the tiny spark as it was happening only at night or w/ very low light. Just fyi, don't do as I did, by attempting to move or touch the wires as the vehicle is running or even when cranking the engine over to start! Haha, okay laugh it up, but if it happens to you (or when) you'll surely find it to be a rather "shocking" experience!!
On a side note, I think this may have also been related to a problem I had (only on occasion for some reason) w/ the van not starting or turning over at all. So, after moving and securing the wire as they should be, (fastened to a plastic retaining clip/clasp that holds them in place), the annoying clicking - ticking noise had completely stopped occuring. If this could be the issue anyone is having, I hope this might help you out!
Good Luck!
P.S. although mine held up for awhile, your wire(s) may need to be replaced w/ new ones. And, I suppose this could happen to almost any model vehicle really, so I wouldn't rule this out when troubleshooting similar issues.
